This invention relates to apparatus for universally 'niounting'ja Working instrument hereinafter appear and T the invention is shown by-vvayof illustration in the accompanying drawings 1n Wh1ch- Fig. 1 is a top plan vlew of" the apparatus; Fig. 2 is'a'yertical, sectional elevation of the apparatus -shown in Fig. 1 ;'and Fig. 3wis an end view of the'apparatus.

Referring to "the drawings, the apparatus cbn'i'prises an upright rectangular frame having setsot legs 1 and 2 which consist of I-beams and are suitably connected to- "gether as by rivets their upper-endsby sets of cross braces 3an'd '4. Movable vertically Within the-upright frame is a rectangular carriagef'rame. consisting of'pairs of I-beams 5 and 6 su tably connected together as by rivets and braced in any usual or Well known manner. Suitably secured to the ends of the I-beams 6 of the carriage frame are U-shaped guide members 7 which embrace the adjacent legs of the upright frame so that in this manner the vertical movement of the carriage frame is guided relative to the upright. frame.

For raising the carriage frame a rotatable shaft 8 is supported in bearing blocks 9 and 10 on top of the cross braces 1 of the upright frame and cables 11 are Wound around the shaft 8 for a portion of their length, extend over pulleys 12 connected to the braces 3 of the upright frame and are connected at their ends to hook bolts 13 which are. fixed to the carriage frame. It will thus be seen that rotation of the shaft 8 in one direction Winds the cables thereon and in this manner hoists the carriage frame to the desired vertical position, and rotation of the shaft 8 in the opposite direction serves to permit the carriage frame to lower itself by its own Wei ht.

In order to rotate the shaft 8, a gear 1 1 is fixed to the shaft. and meshing with the gear 14 is a pinion 15 supported on one end of a stub shaft 16to which a sheave 17'is first. at theopposite end. An endless cable 18 maybe-trainedover the sheave Use that theoperato-r may manually rotate: the sheave 17 inthe' desired direction for raising =0r lowering the carriage frame to the proper vertical position.

Movable laterally along-the I-beams 5, is a carriage having U-shaped housings r 19 "which enclose the Lb'eams or rails 5 and for supporting'thecarriage on the rails 5 pairs of rollers '20'are arranged Within the houS- 'ings 1'9 .and engage therails 5. lnfthis in stance there is 'apair ofrollers' in each housing and,- of each: pair is connected by a-shaft21 Which is fixedly connected thereto. 7 Provided 7 on "the ends of therollers of each pair are 1 sprockets 22 which are'connected by chains 23. It will thus be seen that rotation of the" shaft 21 conjointly drives.-the"-rollers"of xbothsets.

Fordriving the shaft 21 a bevelagean23 is :fixed thereto and meshing Wi tlr thewgear operating crank handle 25. lEnclosih'g the gears 23 and 24 and forrninga support for 7 thegea-r 2 1 is a'ho using' 26 WlllClI'lS. fixed to one of the U-shaped housings :19 by pinzl27 Which extends through the housing 19 and is held in place by a cotter pin 28. A pin 29 extends through the opposite housing 19 and is held in position by a cotter pin 30.

Supported on the U-shaped housing member 19 is a Working tool Which, in this instance, is a device for cleaning the fines of boilers and the like. The flue cleaner con sists of an elongate cylinder 31 Which is held in place by U-bolts 32 Which extend through apertures in the housing member 19 and are engaged by nuts 33. The opposite ends of the cylinder 31 are closed by plugs 34 and arranged Within the cylinder 31 is a piston 35 having a piston rod. 36 Which is adapted to carry at its outer end a brush or other Working instrument, buffer springs 37 being arranged at opposite ends of the cylinderfor receiving the blow of the piston 35.

The piston 35 is actuated by fluid pressure as indicated; anuopposed roller Which may be steam or compressed air and Which is admitted alternately to the opposite ends of the cylinder 31 through a pipe 38. The passage of fluid to the cylinder 31 may be controlled by any suitable valve mechanism within the valve box 39, in this instance a manual control being-provided by means of a handle operatively associated with the .plane may be adjusted by pulling on the endless cable 18 in orderto raise or lower the frame so as to position the piston 86 of the working tool in proper vertical relation. Thereafter theproper lateral position of the piston rod 37 may be controlled by manipulating the crank handle 25 to move the carriage frame laterally in one direction or the other. In this manner complete freedom of movement is obtained and the Working tool may be readily and conveniently positioned accurately with respect to the Work.

WVhile I have shown and describeda construction which is the best form known to me at the present time, it is to be understood that numerous changes in detailsof construction, arrangement and application may be eifectedwithout departing from the spirit of the invention, especially .as defined in the appended claims. It is further to be un'derstood that the invention is not limited solely for use in connection with a fine cleaner.

because its application is much more comprehensive and'may be admirably used to advantage in a variety of situations.

What I claimas new and desiregto secure byLetters Patent, is

e 1. In an apparatus of the class described,

the combination of a rectangular upright frame, a carriage frame in said upright frame, U-shaped guides on said carriage frame engaging said upright frame for guiding the movements of said carriage frame, means on the upper portion of said uprightframe for raisingsaid carriage frame, said means including a rotatable shaft and cables connecting said shaft and carriage frame, a carriage on said carriage frame and movable laterally thereon, pairs of rollers for supporting said carriage, mean forconnecting said rollers for conjointoperation and manually operable means for driving said rollers.

'2. In an apparatus of'the'class described, the combination of a carriage frame having spaced parallel rails, a carriage mova'oie on said rails and having U-shaped housings embracing said rails, rollers in said housings, for supporting said carriage and movable on said rails and means for. conjointly driving said rollers thereby to propel said carriage in one direction or another. 7

3. In an apparatus of the class described, the combination of a carriage frame having parallel spaced rails, a carriage having U shaped housings enclosing said rails, pairs of rollers in said housings engaging said rails for supporting said carriage, a shaft fixed to opposed rollers and rotatable therewith, a chain and sprocket connection between the rollers of each pair, and means for rotating said shaft for conjointly driving said rollers thereby to propel said carriage in one direction or another.

In testimony whereof I have hereunto signed my name to this specification.
